Help Fixing Shower Threshold

How bad is the slope? Like is it 1/8"? More or less? They make a type of threshold that you can put down to sort of dam the water back. They say they're 1/4" tall, but really they are closer to 3/16" tall. You can't order from that site I linked to as it's wholesale, but you can find resellers that have it. Some local glass shops might have them, too. I always keep some in stock.

Cut it to where it's tight against the wall and the side panel, and then apply a decent amount of silicone and stick it down. It also helps to dam up the sides a little bit. If your curb is made up of multiple tiles and not a single piece of stone, then there's a good chance you have grout lines that funnel water out under the sweep. Make sure the silicone you apply to that threshold insert seals up those grout lines.

You will never get it to keep from leaking, but you can slow it down. We've literally installed 1000's of shower enclosures, and every single one that had a mis-sloped curb has never not leaked. I always check them when I measure for the glass and let the homeowner/contractor know that it will leak and I will not warranty it for leaks.

I don't know much about coburns. Just google CRL Shower Threshold and it should bring back quite a few retailers. It looks like there are even some on Amazon.

Thanks again man. I just ordered on off Amazon. I appreciate it.

We must have the same shower. I installed one of the thresholds, it works fairly well. Agree with caulking at the edges and grout line. Try not to get too heavy handed with a caulking, or it'll take forever to dry clear.

I do think it's somewhat ruins the aesthetics of the frameless shower, but what can you do aside from retiling the curb.
